DESCRIPTION

M62301 semiconductor integrated circuit forms an integrating A-D converter,being connected to a microcomputer unit. By using selection signals and counter clock signals from the unit,a 10~12-bit A-D converter can be created at a low cost.

The integration time and resolution can be set at the user‘s option by changing external parameters.In addition,the built-in circuit offset,delay time and temperature fluctuation are adjustable,enabling a wide range of applications.

M62301 has a 3 input decoder circuit,high-precision reference voltage(1.22V)generator,current supply and comparator for integration,and voltage-monitoring reset circuit for a 5V power supply.It is also equipped with girdling to prevent current leak from integration capacitor.

FEATURES

•Separate power supplies for analog section and digital section.

•Low power dissipation.....................................2mA(typ)

(1mA for A-D conversion and the other 1mA for reset)

•Linear error......................................................±0.02(typ)

•Conversion time...............................................526µs/ch(typ)

•Built-in system reset.........................................4.45V(typ)

APPLICATION

High-precision control systems such as temperature control and speed control
